Detecting sharing of passwords for password protected user accounts

ABSTRACT

A method for detecting the sharing of a password related to a password protected user account provided by an organization, by multiple entities of the organization is disclosed. In one embodiment, input associated with a training word is received from a user of a user computing device. In some examples, the input may include a sequence of user input entries related to the training word. In some embodiments, metadata associated with the sequence of user input entries is derived and a user input pattern profile is generated based on the metadata. In some embodiments, an authorized user of the organization is identified based at least in part on comparing the received input to the user input pattern profile.

BACKGROUND OF THE INVENTION

Organizations generally utilize multiple password protected user accounts for providing secure access to computing resources within the organization. These resources may include, for example, software products, applications (e.g., cloud-based applications, enterprise applications, or any other applications), cloud services, various types of data (e.g., networked files, directory information, databases, or the like) and other resources. In order to effectively keep track of resource access by users within an organization, an organization may often use a generic password protected user account with a single password that may be shared among a set of users of the organization. However, sharing passwords may pose several challenges.

Multi-factor authentication has been traditionally used as an authentication mechanism to protect access to user accounts on computing systems. In addition to a username and password to gain access to various resources of the organization, during multi-factor authentication, users may present additional evidence of their identity via one or more other factors. These additional factors may include for example, an authentication token from a token generating device, a scan of a fingerprint, or a one-time code sent to the user's email account or via SMS. However, adding an additional factor to a password-based authentication is inconvenient for users as they need extra devices (token generator, biometric scanner, email account, mobile phone and the like) and time to receive and enter the code. While various techniques have been employed to effectively share such codes or tokens with only intended parties, the employed techniques are of varied success.

BRIEF SUMMARY OF THE INVENTION

Techniques described herein include a method and system for detecting the sharing of a password related to a password protected user account provided by an organization, by multiple entities of the organization. In one embodiment, a challenge word and/or a training word is provided to users of an organization that enables the organization to detect if a password protected user account is being shared across multiple users of the organization. In certain embodiments, techniques are provided (e.g., a method, a system, non-transitory computer-readable medium storing code or instructions executable by one or more processors) for providing account management services to users of an organization. In one embodiment, an account management system is disclosed that provides the ability for multiple entities of the organization to provide account management services to users of the organization.

In some aspects, the organization may be part of a distributed system, described herein. In some examples, the distributed system may comprise a network of subsidiary and/or affiliate systems (e.g., kiosks, franchise stores, corporations and the like) that may be managed, hosted and/or controlled by the organization. The network of affiliate systems, may, in turn be managed by one or more entities (e.g., users, account administrators, support users) of the organization using one or more computing devices such as a mobile phone, a smart phone, a personal digital assistant (PDA), a laptop computer, a desktop computer, a kiosk, a thin-client device, a tablet PC and the like.

In accordance with some embodiments, one or more entities (e.g., account administrators) of the organization may utilize a generic account provided by the account management system to access one or more account management services. These services may include, for example, provisioning accounts to users of the organization. In one embodiment, a method is disclosed to determine inappropriate access to the generic account by the one or more entities of the organization by identifying the number of entities sharing the generic account.

In accordance with at least one embodiment, a user (e.g., an account administrator) on a computing device (e.g., a kiosk computer) may access an application (e.g., an account provisioning application) provided by the account management system to login to a generic account. In some examples, the user may be requested to input a training word during login. In some examples, the training word may include a string of characters (e.g., a combination of letters and numbers) of a predetermined character length that is provided to the user. In certain embodiments, the training word may be a randomly selected word from a subset of training words that may not be publically available to the users. Thus, in some examples, the training word may provide an additional layer of security for a user accessing a password protected generic account provided by the organization.

In some examples, the account management system may be configured to receive login information including input associated with the training word from the user to determine whether the login information identifies the user based at least in part on the received input.

In accordance with one set of operations, the account management system may be configured to provide a training word to a user of a user computing device and receive input associated with the training word from the user. In some examples, the input may comprise a sequence of user input entries related to the training word. In another set of operations, the account management system may be configured to derive metadata associated with the sequence of user input entries and generate a user input pattern profile based at least in part on the metadata. In some operations, the account management system may be configured to receive login information from the user computing device and determine whether the login information identifies the user based at least in part on the user input pattern profile.

In accordance with another set of operations, the account management system may be configured to receive an input comprising a sequence of user input entries related to a first training word from a user computing device, receive login information from the user computing device, compare the received input to one or more user input pattern profiles and determine which of a first user or a second user of a plurality of users provided the received input, based at least in part on the comparison of the received input to the one or more user input pattern profiles.

In accordance with yet another set of operations, the account management system may be configured to generate a plurality of computer-generated entries of an image of a word, receive login information from a user computing device, compare input associated with the login information to the plurality of computer-generated entries and a plurality of user input pattern profiles. In some embodiments, the account management system may then determine that the login information identifies a user of the user computing device, based on comparing the input associated with the login information with the computer-generated entries and the user input pattern profiles.

DETAILED DESCRIPTION OF THE INVENTION

The techniques described above and below may be implemented in a number of ways and in a number of contexts. Several example implementations and contexts are provided with reference to the following figures, as described below in more detail. However, the following implementations and contexts are but a few of many.

FIG. 1 depicts aspects of an example system architecture 100 in accordance with at least one embodiment of the present disclosure. The architecture 100 includes an account management system 112 communicatively connected to one or more user computing devices 102(1) . . . 102(n) (collectively, user devices 102) via a network 104. In some examples, the network 104 may include any one or a combination of many different types of networks, such as cable networks, the Internet, wireless networks, cellular networks and other private and/or public networks.

In one embodiment, the account management system 112 may be managed, hosted and/or provided by one or more service provider computers 96, described herein. In certain embodiments, the service provider computers 96 may be configured to provide account management services (e.g., the creation and/or provisioning of user accounts) to the users (e.g., an account administrator) of the user devices 102, via the account management system 112.

In some aspects, the user devices 102 may be part of a distributed system managed by, controlled by, or otherwise part of the service provider computers 96. For example, the user devices 102 may be managed, hosted or provided by a network of affiliate systems (e.g., kiosks, franchise stores, corporations and the like) managed by the service provider 126. In some aspects, one or more users of the user devices 102 may be configured to operate a client application such as a web browser, a proprietary client application or some other application to access services provided by the account management system 112. These services may include, for example, the management and/or provisioning of resources (e.g., subscriber phone accounts) to subscribers of the service provider 126.

In some examples, the service provider computers 126 may also provide computing resources such as, but not limited to, data storage, data access, management, virtualization, cloud-based software solutions, electronic content performance management, and the like. The service provider computers may be operable to provide web hosting, computer application development, and/or implementation platforms, combinations of the foregoing, or the like to the users.

In some aspects, the service provider computers 126 may be any type of computing devices such as, but not limited to, a mobile phone, a smart phone, a kiosk, a personal digital assistant (PDA), a laptop computer, a desktop computer, a server computer, a thin-client device, a tablet PC, etc. Additionally, it should be noted that in accordance with at least one embodiment, the service provider computers may be executed by one more virtual machines implemented in a hosted computing environment. The hosted computing environment may include one or more rapidly provisioned and released computing resources, which computing resources may include computing, networking and/or storage devices. A hosted computing environment may also be referred to as a cloud computing environment. In some examples, the service provider computers 96 may be in communication with the user devices 102 and/or other service providers via the networks 104, or via other network connections. The service provider computers may include one or more servers, perhaps arranged in a cluster, as a server farm, or as individual servers not associated with the account management system 19 described herein as part of an integrated, distributed computing environment.

The user devices 102 may be any type of computing device such as, but not limited to, a mobile phone, a smart phone, a personal digital assistant (PDA), a laptop computer, a desktop computer, a kiosk, a thin-client device, a tablet PC, an electronic book (e-book) reader, etc. In some examples, the user devices 102 may be in communication with the service provider computers 96 via the networks 104, or via other network connections.

In accordance with at least one embodiment, the account management system 112 may include a user authentication module 106, a user input pattern profile generation module 108, an account sharing detection module 110 and a data store 114 accessible to the user authentication module 106, the user input pattern profile generation module 108 and the account sharing detection module 110. The data store 114 may be configured to provide a storage repository for storing information related to the management of log-in credentials by entities accessing services provided by the account management system 19. In some examples, the data store 114 may include a user accounts database 116, a library of computer-generated entries of training words 118, a user input profiles database 120, a user input patterns database 122 and a training dataset 124. The modules (106, 108 and 110) of the account management system 112 may be implemented in software (e.g., program code, instructions executable by a processor), in hardware, or combinations thereof. In some embodiments, the software may be stored in memory (e.g., a non-transitory computer-readable medium), on a memory device, or some other physical memory and may be executed by one or more processing units (e.g., one or more processors, one or more processor cores, one or more GPUs, etc.). Additional details of the operations performed by the various modules (e.g., 106, 108 and 110) are discussed in detail below.

In accordance with at least one embodiment, the user input pattern profile generation module 108 may be configured to provide a training word to a user of a user device 102 when the user registers with and/or logs into a generic account provided by the account management system 112, from the user device 102. In some examples, the training word may include a string of characters (e.g., a combination of letters and numbers) of a predetermined character length that is provided to the user. In other examples, the training word may also include an image of a string of a predetermined character length. For example, the image of a string may include a Completely Automated Public Turing test to tell Computers and Humans Apart (CAPTCHA) image of an alphanumeric string that may be presented to the user when the user logs into the generic account. In some examples, the CAPTCHA image may include an image of a training word or an image chosen by a user to associate with a training word stored in the training dataset 124. In some embodiments, the user input pattern generation module 108 may be configured to randomly select a training word from a subset of training words stored in the training dataset 128. Thus, a user may be provided with the same training word, in some examples, or a different training word from the subset of training words, in other examples each time a user registers with and/or logs into the generic account.

In accordance with at least some embodiments, the user input pattern profile generation module 108 may be configured to receive input associated with the training word from the user. In some examples, the input may correspond to a sequence of user input entries related to the training word. In some examples, the input may be received via input devices such as a keyboard, keypad, mouse, trackball, a touchpad and/or a touch screen incorporated into a display of the user device 102. In other embodiments, the input may also be received via input devices such as voice command recognition systems, microphones and motion sensing and/or gesture recognition devices that receive user input using gestures and spoken commands. In some examples, the input may also be received via eye gesture recognition devices that detect eye activity (e.g., ‘blinking’) from a user.

In some examples, the sequence of user input entries may represent a series of actions performed by the user in relation to the training word. The actions may include, for example, a press or a release of a particular key, a press or a release of a pointing device such as a mouse or touch pad, and/or a press or release of a finger by the user as the user inputs the training word into the input device. The actions may also include the user saying the training word via a voice input, the user blinking to input the training word or the user making a gesture (e.g., waving hands) to input the training word.

In some embodiments, the sequence of user input entries may be represented as a time-series of events, wherein each event may correspond to an action performed by the user. In some examples, the user input pattern generation module 108 may be configured to store the input (i.e., a sequence of user input entries) corresponding to the training word in a user input patterns database 122.

In accordance with at least some embodiments, the user input pattern profile generation module 108 may be configured to generate a user input pattern profile based at least in part on the sequence of user input entries. In some examples, the user input pattern profile may be stored in the user input profiles database 120. The manner in which the user input pattern profile generation module 116 may generate a user input pattern profile is discussed in relation to FIG. 2.

In accordance with some examples, the user input pattern profile generation module 108 may also be configured to receive input associated with the login information from the user in addition to the input associated with the training word. For example, the received input may include a sequence of user input entries corresponding to the username and password entered by the user. In some examples, the user input pattern profile generation module 108 may be configured to store input related to the login information in the user input patterns database 122. Thus, in some examples, the user input pattern profile may also be generated based at least in part on the input related to the login information stored in the user input patterns database 122.

In accordance with at least one embodiment, the account sharing detection module 110 may be configured to compare the input received from the user to one or more user input pattern profiles stored in the user input profiles database 120. Based at least in part on the comparing, in some examples, the account sharing detection module 110 may be configured to determine if the user accessing the generic account is an authorized user of the account management system 112. In some embodiments, the account sharing detection module 110 may be configured to identify the number of users who have shared access to the generic account based at least in part on the number of identified user input pattern profiles. The identification of users based on the generated user input pattern profiles is discussed in detail in relation to FIG. 2.

In accordance with at least some embodiments, the account management system 112 may also be configured to obtain a plurality of computer-generated entries of a subset of training words. In some examples, the plurality of computer-generated entries may correspond to computer-generated entries of images of a string. In some examples, the entries may be generated by one or more modules of the account management system 112 by simulating typing rhythms of access credentials typed by users when users register and/or log into applications and/or resources provided by the account management system 122.

In accordance with some embodiments, the account sharing detection module 118 may be configured to compare the received input from the user device 102 to the user input pattern profile profiles stored in the user input profiles database 120 and the computer-generated entries of a subset of training words stored in the library of computer generated entries 118. In some examples, based at least in part on the comparing, the account sharing detection module 118 may then be configured to determine if the received input corresponds to a registered user of the account management system 112 or a computer-generated entry of a training word not associated with a user of the account management system 112. For example, based on the comparing, the account management system 112 may determine that the received input is generated from an automated program and/or application, such as a bot attempting to gain unauthorized access into the account management system 112.

In accordance with at least some embodiments, the user authentication module 106 may be configured to either grant access or deny access to a user of the account management system 112 based at least in part on the input received from the account sharing detection module 110. For example, if the account sharing detection module 110 determines that the user is an authorized user of the system, the user authentication module 106 may grant access to the user by comparing the login credentials of the user stored in the user accounts database 116 to the login information input by the user. If the account sharing detection module 110 determines that the user is not an authorized user of the system, the user authentication module 106 may either request the user to re-enter the login credentials or deny the user access into the system. In some embodiments, the user authentication module 106 may log all attempts to authenticate a user into the system, including information related to the received input from the user such as a sequence of user input entries related to one or more training words input by the user. In some examples, this information may be utilized by the user authentication module 106 to detect information related to the sharing of passwords and/or for auditing purposes. Additionally, in some examples, the user accounts database 116 may store information that authenticates the identities of users of the account management system 112 and information that describes which actions those users are authorized to perform relative to various system resources (e.g., files, directories, applications, communication ports, memory segments, etc.)

In some embodiments, once the user is authenticated, the user authentication module 106 may send a notification to the user indicating that the requested service is now available for use. In some instance, information (e.g. a link) may be sent to the user that enables the user to start using the requested services.

FIG. 2 is an exemplary illustration of the generation of user input pattern profiles, in accordance with one embodiment of the present disclosure. In one embodiment, the user input pattern profiles may be generated by the user input pattern profile generation module 108 discussed in relation to FIG. 1. In certain embodiments, the user input pattern profile module 108 may be configured to analyze one or more data sets (e.g., 202, 204, 206, 208 and 210) stored in the user input patterns database 122. In some examples, the one or more data sets 202, 204, 206, 208 and 210 may include a set of samples corresponding to a sequence of user input entries related to a training word input by one or more users of the user devices 102. Additionally, in some examples, each sample in the one or more data sets (e.g., 202, 2041, 206, 208 and 210) may relate to a training word that may be input by the same user or a different user of the user devices 102

In accordance with at least some embodiments, the user input pattern profile generation module 108 may be configured to generate the one or more user input pattern profiles based at least in part on deriving metadata related to sequence of user input entries corresponding to each sample of the data sets 202, 204, 206, 208 and 210. In one example, the metadata may include user input timing information related to a sequence of user input entries corresponding to a sample of a data set. In some examples, user input timing information may include, for example, the dwell time of a key ‘x’, the flight time of a key ‘x’ or the latency of a key ‘x’ of a user typing a training word. As described herein, the dwell time of a key ‘x’ may measure the time interval from the time at which the key ‘x’ was pressed to the time at which the key ‘x’ was released. The flight time may measure the time interval at which a key ‘x’ was released to the time at which a next key was pressed. The latency may measure the time interval from the time at which a key ‘x’ was pressed to the time the next key was pressed. In other examples, the user input timing information may include, measuring the dwell time, the flight time and/or the latency of the press and/or the release of the user's finger on a touch screen or touchpad utilized by the user to type the training word and/or the press and/or release of an input device such as a mouse or a trackball utilized by the user to type the training word.

In an example, a sequence of user input entries corresponding to the typing of a training word (‘W’ ‘O’ ‘R’ ‘D’) by a user may be represented as a time-series of events as follows:

{timeFromDisplayToTyping, dt(“w”), ft(“o”), dt(“o”), ft(“r”), dt(“r”), ft(“r”), t(“d”), dt(“d”), ft(advance), dt(advance)} wherein ‘dt(x)’ corresponds to the dwell time of a key ‘x’, ‘ft(x)’ corresponds to the flight time of a key ‘x’ and advance corresponds to a tab key (to go to the next field) or a submit key pressed by a user.

In some examples, the user input pattern profile generation module 108 may be configured to measure the similarity between a pair of samples in the data sets 202, 204, 206, 208 and 210, based at least in part on the user input timing information. In some examples, the similarity between a pair of samples of a data set may be measured based on various metrics. For example, the similarity may be determined by computing the distance between the pair of samples. The distance may be computed, for example, by measuring the Euclidian distance between the pair of samples. Other distance metrics may be used by the user input pattern profile generation module 108, in other examples. In some examples, the similarity between a pair of samples may also be determined by computing the total dwell time and the total flight time of each of the samples.

The user input pattern profile generation module 116 may then be configured to partition the data sets 202, 204, 206, 208 and 210 based at least in part on the determined similarity. For instance, the user input pattern profile generation module 108 may combine one or more samples of the data sets into a single cluster if the distance between a pair of samples in a data set or between data sets is determined to be within a pre-determined threshold value. Or, for example, one or more samples of the data sets may be combined into a single cluster if the total dwell time and the total flight time of the samples are within a pre-determined threshold value. In one embodiment, the resulting clusters may be referred to herein as user input pattern profiles. In one embodiment, the number of user input pattern profiles determined may relate to the number of users sharing access to the generic account. In the example illustrated in FIG. 2, three user input pattern profile clusters (e.g., 212, 214 and 216) are generated, indicative of three users sharing access to the generic account.

In some embodiments, the account sharing detection module 110 (shown in FIG. 1) may determine the number of users who have shared access to the generic account based at least in part on the number of identified user input pattern profiles. In other embodiments, the account sharing detection module 110 may determine that a user is an unauthorized user of the account management system 112 based at least in part on comparing the received input to one or more user input pattern profiles. For instance, if the received input does not match any one of the generated user input pattern profiles, it may be determined that the user is an unauthorized user of the account management system 112. In other embodiments, the account sharing detection module 110 may compare the received input to one or more stored user input pattern profiles in the user input profiles database 120 and the library of computer generated entries 118 to determine if a user or an automated software program is attempting to gain unauthorized access into the system.

FIG. 3 depicts an example sequence diagram of the steps performed by one or more modules of the account management system depicted in FIG. 1, in accordance with one embodiment of the present disclosure. The sequence diagram depicted in FIG. 3 is only an example of the operations performed by the account management system and is not intended to be limiting. In one example, an exemplary sequence of operations performed by the account management system may be as follows:

At (1) the account management system 406 may receive a request from a user device 408 to access an application (e.g., an account provisioning application) provided by the account management system 406.

At (2) the account management system 406 may display the application to the user via a user interface of the user device 408.

At (3) the account management system 406 may receive input related to the training word from the user. Additionally, in some examples, the account management system 406 may also receive input related to the login information input by the user when the user registers with and/or accesses the application via the user device 408.

At (4) the account management system 406 may transmit the received input to the user input pattern profiles generation module 404. The input, in some examples, may include a sequence of user input entries related to the training word and/or the login information input by the user.

At (5), the user input pattern profiles generation module 404 may compare the received input to one or more user input pattern profiles stored in the user input profiles database 120.

At (6), the user input pattern profiles generation module 404 may transmit a notification to the user authentication module 410, based at least in part on the comparing. In some examples, the notification is a message provided to the user authentication module 410 that indicates whether the user is an identified user or an unidentified user of the account management system 406.

At (7), substantially simultaneously, the account management system 406 may also transmit the received input from the user device 408 to the account sharing detection module 402.

At (8), the account sharing detection module 402 may compare the received input with the stored user input pattern profiles and a plurality of computer-generated entries of a subset of training words stored in the library of computer generated entries 118.

At (9), the account sharing detection module 402 may transmit a notification to the user authentication module 410, based at least in part on the comparing. In some examples, the notification is a message provided to the user authentication module 410 that indicates whether the user is an identified user or an automated software program attempting to gain access into the account management system 406.

At (10), if the user is determined to be an identified user, the user authentication module 410 grants the user access to the application. In some examples, the user authentication module 410 may also send a notification to the user device 408 indicating that the requested service is now available for use by the user.

At (11), if the user is determined to be an unauthorized user or an automated software program attempting to gain access into the account management system 406, the user authentication module 410 may deny access to the user and/or prevent the user device from gaining access to the application. In some examples, the user authentication module 410 may also send a notification to the user device 408 indicating that the requested service has been denied to the user and/or may send a notification to the user to request the user to re-enter the login information.

In some embodiments, at (11) a user may be provided with one or more additional training words from the training dataset (e.g., 124). The additional training words may be the same as the original training word, in some examples, or a different training word, in other examples. In some examples, if the input associated with the additional training word matches one or more user input pattern profiles stored in the user input profiles database 120, the user authentication module 410 may authorize the user into the system. In other examples, the user authentication module 410 may lock the user out of the account for a pre-specified period of time, if no match between the received input and the user input pattern profiles are found.

FIG. 4 illustrates an example flow diagram showing respective processes 400, 500 and 600 of providing account management services for users of the account management system, described herein. These processes are illustrated as logical flow diagrams, each operation of which represents a sequence of operations that can be implemented in hardware, computer instructions, or a combination thereof. In the context of computer instructions, the operations represent computer-executable instructions stored on one or more computer-readable storage media that, when executed by one or more processors, perform the recited operations. Generally, computer-executable instructions include routines, programs, objects, components, data structures and the like that perform particular functions or implement particular data types. The order in which the operations are described is not intended to be construed as a limitation, and any number of the described operations can be combined in any order and/or in parallel to implement the process.

Additionally, some, any, or all of the processes may be performed under the control of one or more computer systems configured with executable instructions and may be implemented as code (e.g., executable instructions, one or more computer programs, or one or more applications) executing collectively on one or more processors, by hardware, or combinations thereof. As noted above, the code may be stored on a computer-readable storage medium, for example, in the form of a computer program including a plurality of instructions executable by one or more processors. The computer-readable storage medium may be non-transitory. In some examples, the account management system 112 (e.g., utilizing at least the user authentication module 106, the user input pattern profiles generation module 108 and the account sharing detection module 110) shown in at least FIG. 1 (and others) may perform the processes 400, 500 and 600 of FIG. 4, FIG. 5 and FIG. 6 respectively.

FIG. 4 illustrates a flow diagram of an example process 400 for providing account management services offered by the account management system, described herein. The process at 400 may begin at 402 by providing a training word to a user of a user computing device (e.g., 102). At 404, the process at 400 may include receiving input associated with the training word from the user. In some examples, the input may include a sequence of user input entries related to the training word. At 406, the process at 400 may include deriving metadata associated with the sequence of user input entries. Metadata associated with the sequence of user input entries may include, for example, user input timing information such as the dwell time, flight time or latency related to the sequence of user input entries. At 408, the process at 400 may include generating a user input pattern profile based at least in part on the received input. In some examples, at 410, the process 400 may include receiving login information from the user computing device.

In some embodiments, the account management services described above may be offered as services via a cloud environment. FIG. 8 is a simplified block diagram of one or more components of a system environment 800 in which services may be offered as cloud services, in accordance with an embodiment of the present disclosure. In the illustrated embodiment in FIG. 8, system environment 800 includes one or more client computing devices 804, 806, and 808 that may be used by users to interact with a cloud infrastructure system 802 that provides cloud services, including services for dynamically modifying documents (e.g., webpages) responsive to usage patterns. Cloud infrastructure system 802 may comprise one or more computers and/or servers that may include those described above for server 712.

It should be appreciated that cloud infrastructure system 802 depicted in FIG. 8 may have other components than those depicted. Further, the embodiment shown in FIG. 8 is only one example of a cloud infrastructure system that may incorporate an embodiment of the invention. In some other embodiments, cloud infrastructure system 802 may have more or fewer components than shown in the figure, may combine two or more components, or may have a different configuration or arrangement of components.

Client computing devices 804, 806, and 808 may be devices similar to those described above for 702, 704, 706, and 708. Client computing devices 804, 806, and 808 may be configured to operate a client application such as a web browser, a proprietary client application (e.g., Oracle Forms), or some other application, which may be used by a user of the client computing device to interact with cloud infrastructure system 802 to use services provided by cloud infrastructure system 802. Although exemplary system environment 800 is shown with three client computing devices, any number of client computing devices may be supported. Other devices such as devices with sensors, etc. may interact with cloud infrastructure system 802.

Network(s) 810 may facilitate communications and exchange of data between clients 804, 806, and 808 and cloud infrastructure system 802. Each network may be any type of network familiar to those skilled in the art that can support data communications using any of a variety of commercially-available protocols, including those described above for network(s) 710.

In certain embodiments, services provided by cloud infrastructure system 802 may include a host of services that are made available to users of the cloud infrastructure system on demand. In addition to services related to account management, various other services may also be offered including without limitation online data storage and backup solutions, Web-based e-mail services, hosted office suites and document collaboration services, database processing, managed technical support services, and the like. Services provided by the cloud infrastructure system can dynamically scale to meet the needs of its users.

In certain embodiments, a specific instantiation of a service provided by cloud infrastructure system 802 may be referred to herein as a “service instance.” In general, any service made available to a user via a communication network, such as the Internet, from a cloud service provider's system is referred to as a “cloud service.” Typically, in a public cloud environment, servers and systems that make up the cloud service provider's system are different from the customer's own on-premises servers and systems. For example, a cloud service provider's system may host an application, and a user may, via a communication network such as the Internet, on demand, order and use the application.

In some examples, a service in a computer network cloud infrastructure may include protected computer network access to storage, a hosted database, a hosted web server, a software application, or other service provided by a cloud vendor to a user, or as otherwise known in the art. For example, a service can include password-protected access to remote storage on the cloud through the Internet. As another example, a service can include a web service-based hosted relational database and a script-language middleware engine for private use by a networked developer. As another example, a service can include access to an email software application hosted on a cloud vendor's web site.

In certain embodiments, cloud infrastructure system 802 may include a suite of applications, middleware, and database service offerings that are delivered to a customer in a self-service, subscription-based, elastically scalable, reliable, highly available, and secure manner. An example of such a cloud infrastructure system is the Oracle Public Cloud provided by the present assignee.

Cloud infrastructure system 802 may also provide “big data” elated computation and analysis services. The term “big data” is generally used to refer to extremely large data sets that can be stored and manipulated by analysts and researchers to visualize large amounts of data, detect trends, and/or otherwise interact with the data. This big data and related applications can be hosted and/or manipulated by an infrastructure system on many levels and at different scales. Tens, hundreds, or thousands of processors linked in parallel can act upon such data in order to present it or simulate external forces on the data or what it represents. These data sets can involve structured data, such as that organized in a database or otherwise according to a structured model, and/or unstructured data (e.g., emails, images, data blobs (binary large objects), web pages, complex event processing). By leveraging an ability of an embodiment to relatively quickly focus more (or fewer) computing resources upon an objective, the cloud infrastructure system may be better available to carry out tasks on large data sets based on demand from a business, government agency, research organization, private individual, group of like-minded individuals or organizations, or other entity.

In various embodiments, cloud infrastructure system 802 may be adapted to automatically provision, manage and track a customer's subscription to services offered by cloud infrastructure system 802. Cloud infrastructure system 802 may provide the cloud services via different deployment models. For example, services may be provided under a public cloud model in which cloud infrastructure system 802 is owned by an organization selling cloud services (e.g., owned by Oracle Corporation) and the services are made available to the general public or different industry enterprises. As another example, services may be provided under a private cloud model in which cloud infrastructure system 802 is operated solely for a single organization and may provide services for one or more entities within the organization. The cloud services may also be provided under a community cloud model in which cloud infrastructure system 802 and the services provided by cloud infrastructure system 802 are shared by several organizations in a related community. The cloud services may also be provided under a hybrid cloud model, which is a combination of two or more different models.

In some embodiments, the services provided by cloud infrastructure system 802 may include one or more services provided under Software as a Service (SaaS) category, Platform as a Service (PaaS) category, Infrastructure as a Service (IaaS) category, or other categories of services including hybrid services. A customer, via a subscription order, may order one or more services provided by cloud infrastructure system 802. Cloud infrastructure system 802 then performs processing to provide the services in the customer's subscription order.

In some embodiments, the services provided by cloud infrastructure system 802 may include, without limitation, application services, platform services and infrastructure services. In some examples, application services may be provided by the cloud infrastructure system via a SaaS platform. The SaaS platform may be configured to provide cloud services that fall under the SaaS category. For example, the SaaS platform may provide capabilities to build and deliver a suite of on-demand applications on an integrated development and deployment platform. The SaaS platform may manage and control the underlying software and infrastructure for providing the SaaS services. By utilizing the services provided by the SaaS platform, customers can utilize applications executing on the cloud infrastructure system. Customers can acquire the application services without the need for customers to purchase separate licenses and support. Various different SaaS services may be provided. Examples include, without limitation, services that provide solutions for sales performance management, enterprise integration, and business flexibility for large organizations.

In some embodiments, platform services may be provided by cloud infrastructure system 802 via a PaaS platform. The PaaS platform may be configured to provide cloud services that fall under the PaaS category. Examples of platform services may include without limitation services that enable organizations (such as Oracle) to consolidate existing applications on a shared, common architecture, as well as the ability to build new applications that leverage the shared services provided by the platform. The PaaS platform may manage and control the underlying software and infrastructure for providing the PaaS services. Customers can acquire the PaaS services provided by cloud infrastructure system 802 without the need for customers to purchase separate licenses and support. Examples of platform services include, without limitation, Oracle Java Cloud Service (JCS), Oracle Database Cloud Service (DBCS), and others.

By utilizing the services provided by the PaaS platform, customers can employ programming languages and tools supported by the cloud infrastructure system and also control the deployed services. In some embodiments, platform services provided by the cloud infrastructure system may include database cloud services, middleware cloud services (e.g., Oracle Fusion Middleware services), and Java cloud services. In one embodiment, database cloud services may support shared service deployment models that enable organizations to pool database resources and offer customers a Database as a Service in the form of a database cloud. Middleware cloud services may provide a platform for customers to develop and deploy various business applications, and Java cloud services may provide a platform for customers to deploy Java applications, in the cloud infrastructure system.

Various different infrastructure services may be provided by an IaaS platform in the cloud infrastructure system. The infrastructure services facilitate the management and control of the underlying computing resources, such as storage, networks, and other fundamental computing resources for customers utilizing services provided by the SaaS platform and the PaaS platform.

In certain embodiments, cloud infrastructure system 802 may also include infrastructure resources 830 for providing the resources used to provide various services to customers of the cloud infrastructure system. In one embodiment, infrastructure resources 830 may include pre-integrated and optimized combinations of hardware, such as servers, storage, and networking resources to execute the services provided by the PaaS platform and the SaaS platform, and other resources.

In some embodiments, resources in cloud infrastructure system 802 may be shared by multiple users and dynamically re-allocated per demand. Additionally, resources may be allocated to users in different time zones. For example, cloud infrastructure system 802 may enable a first set of users in a first time zone to utilize resources of the cloud infrastructure system for a specified number of hours and then enable the re-allocation of the same resources to another set of users located in a different time zone, thereby maximizing the utilization of resources.

In certain embodiments, a number of internal shared services 832 may be provided that are shared by different components or modules of cloud infrastructure system 802 to enable provision of services by cloud infrastructure system 802. These internal shared services may include, without limitation, a security and identity service, an integration service, an enterprise repository service, an enterprise manager service, a virus scanning and white list service, a high availability, backup and recovery service, service for enabling cloud support, an email service, a notification service, a file transfer service, and the like.

In certain embodiments, cloud infrastructure system 802 may provide comprehensive management of cloud services (e.g., SaaS, PaaS, and IaaS services) in the cloud infrastructure system. In one embodiment, cloud management functionality may include capabilities for provisioning, managing and tracking a customer's subscription received by cloud infrastructure system 802, and the like.

In one embodiment, as depicted in FIG. 8, cloud management functionality may be provided by one or more modules, such as an order management module 820, an order orchestration module 822, an order provisioning module 824, an order management and monitoring module 826, and an identity management module 828. These modules may include or be provided using one or more computers and/or servers, which may be general purpose computers, specialized server computers, server farms, server clusters, or any other appropriate arrangement and/or combination.

In an exemplary operation, at 834, a customer using a client device, such as client device 804, 806 or 808, may interact with cloud infrastructure system 802 by requesting one or more services provided by cloud infrastructure system 802 and placing an order for a subscription for one or more services offered by cloud infrastructure system 802. In certain embodiments, the customer may access a cloud User Interface (UI) such as cloud UI 812, cloud UI 814 and/or cloud UI 816 and place a subscription order via these UIs. The order information received by cloud infrastructure system 802 in response to the customer placing an order may include information identifying the customer and one or more services offered by the cloud infrastructure system 802 that the customer intends to subscribe to.

At 836, the order information received from the customer may be stored in an order database 818. If this is a new order, a new record may be created for the order. In one embodiment, order database 818 can be one of several databases operated by cloud infrastructure system 818 and operated in conjunction with other system elements.

At 838, the order information may be forwarded to an order management module 820 that may be configured to perform billing and accounting functions related to the order, such as verifying the order, and upon verification, booking the order.

At 840, information regarding the order may be communicated to an order orchestration module 822 that is configured to orchestrate the provisioning of services and resources for the order placed by the customer. In some instances, order orchestration module 822 may use the services of order provisioning module 824 for the provisioning. In certain embodiments, order orchestration module 822 enables the management of business processes associated with each order and applies business logic to determine whether an order should proceed to provisioning.

As shown in the embodiment depicted in FIG. 8, at 842, upon receiving an order for a new subscription, order orchestration module 822 sends a request to order provisioning module 824 to allocate resources and configure resources needed to fulfill the subscription order. Order provisioning module 824 enables the allocation of resources for the services ordered by the customer. Order provisioning module 824 provides a level of abstraction between the cloud services provided by cloud infrastructure system 800 and the physical implementation layer that is used to provision the resources for providing the requested services. This enables order orchestration module 824 to be isolated from implementation details, such as whether or not services and resources are actually provisioned on the fly or pre-provisioned and only allocated/assigned upon request.

At 844, once the services and resources are provisioned, a notification may be sent to the subscribing customers indicating that the requested service is now ready for use. In some instance, information (e.g. a link) may be sent to the customer that enables the customer to start using the requested services.

At 846, a customer's subscription order may be managed and tracked by an order management and monitoring module 826. In some instances, order management and monitoring module 826 may be configured to collect usage statistics regarding a customer use of subscribed services. For example, statistics may be collected for the amount of storage used, the amount data transferred, the number of users, and the amount of system up time and system down time, and the like.

In certain embodiments, cloud infrastructure system 800 may include an identity management module 828 that is configured to provide identity services, such as access management and authorization services in cloud infrastructure system 800. In some embodiments, identity management module 828 may control information about customers who wish to utilize the services provided by cloud infrastructure system 802. Such information can include information that authenticates the identities of such customers and information that describes which actions those customers are authorized to perform relative to various system resources (e.g., files, directories, applications, communication ports, memory segments, etc.) Identity management module 828 may also include the management of descriptive information about each customer and about how and by whom that descriptive information can be accessed and modified.
